can provide a strict guarantee on the number of detectable errors, but it may not protect against a preimage attack.

Repetition codes

A repetition code is a coding scheme that repeats the bits across a channel to achieve error-free communication. Given a stream of data to be transmitted, the data are divided into blocks of bits. Each block is transmitted some predetermined number of times. For example, to send the bit pattern , the four-bit block
